6:13 PM LOCAL TIMEJohn Muir Wilderness is a high-country realm of glacial valleys, steep granite domes, and crystal-clear lakes in the Sierra Nevada. Named after the pioneering conservationist John Muir, the reserve spans roughly 2,000 square kilometers across multiple counties. Visitors come for seasonal hiking, backcountry camping, and mountain routes—key trailheads include Tuolumne Meadows, Devereaux Meadow, and Rainbow Falls. The area's elevations reach over 14,000 feet, supporting species like bighorn sheep and Muir Trail-endemic Clark's nutcracker. While largely undeveloped, the wilderness offers dramatic scenery and access to iconic peaks like Mount Lyell and Silicon Valley-area landmarks. Prepare for variable weather, high altitudes, and long-distance hiking; permits are required for overnight stays.
